This rule is originally a variant of FattyLife (B3-n4nt5qr6i/S23), but adds the glider and numerous mangled-WSS ships that weren't in the original rule. So many, in fact, that I decided to name the rule FishLife (as WSSes were once referred to as fishes).

The original posts on the rule from the Miscellaneous Discoveries thread:

In addition, it is worth noting this rule has one of the highest objects/sec (as opposed to soups/sec) searching speeds I've ever seen with apgsearch - comparable with regular B3/S23, which has numerous rule-specific speedups in the code itself.

It seems like a one-dimensional CA of sorts (first I thought it was XOR, but it's more complicated than that), except there's two "layers" of such 1D CAs interacting. It's a definitely unusual behaviour which I haven't seen in other rules before.

Catagolue hasn't found any more single-WSS ships despite the rule now having the second-most objects on Catagolue of any isotropic non-totalistic rule (!), suggesting there isn't such an infinitely extendable family, though flotillas of multiple fishes have appeared. Indeed, a simple attempt to extend this OWSS (the longest one) results in the ship simply shedding the extra weight:

Interestingly, around generation 66 there briefly appears a WSS-front heading in the opposite direction to the rest of the ship. Were the earlier debris not present, it would evolve into a second fish:
